I have uploaded new builds of the content installer power toys to the Got Dot NET workspace at http://workspaces.gotdotnet.com/CCIPowerToys. This package was built with a RC build of VS, so you may need a newer version to use it.
This version has a number of bug fixes (including fixing the problem loading the Zip library), and new features. I have also split setup of the tools into 2 seperate MSI files. One has just the custom content installers (help installer, code library installer, visualizer installer, etc). The other MSI file contains the client side tools, the content builder, content uninstaller, and templates used to build your own custom installers.
I have also posted a new build of the Community Content Web Hosting Site template. Download the zip file (do not extract it, it is a template package) and copy it directly to My Documents\Visual Studio 2005\Templates\ProjectTemplates.
